Filter Integrity Test

Dispersed Oil Particulate (DOP) testing, also known as filter integrity testing, is the process in which the integrity of your HEPA (High Efficiency Particulate Air) or ULPA (Ultra Low Penetration Air) filter is challenged through introducing particulates and measuring the output.

PAO testing is a very quick process that tests the integrity of the HEPA (High Efficiency Particulate Air) filter using DOP or PAO solutions in their operational conditions. These solutions generate a gas type smoke and then generate gas particles that will be greater than . 03 microns.PAO testing is a very quick process that tests the integrity of the HEPA (High Efficiency Particulate Air) filter using DOP or PAO solutions in their operational conditions.
